ad9176 channel interpolation issue

Category: Software
Product Number: ad9176_ebz, ad9176

Hi 

based on ad9176 datasheet

in mode4 and single link mode, channel interplation should be 2x or 3x but in https://github.com/analogdevicesinc/linux/blob/2021_R2/arch/arm64/boot/dts/xilinx/zynqmp-zcu102-rev10-ad9172-fmc-ebz-mode4.dts,  adi,channel-interpolation = <4>; and there isn't adi,dual-link property this means this node is in single-link so channel-interpolation should be 2 or 3, why this is 4, and when i set this property to 3 for example jesd_status is:

and i attach my iio_info output in this situation,

    so 2x6, 2x8, 3x6, 3x8 is for only one (single or dual)? can you clear this for me?

    Those are valid values for single and dual link, as long as you don't violate the max channel NCO clock…

  • I would read this table differently. 4x8 is a valid configuration for both single and dual.

    Can you please provide your exact dts modifications?

    It's likely the case that the clock chip needs a different configuration if you change the interpolation factors...

  • 4x8 is a valid configuration for both single and dual

    so 2x6, 2x8, 3x6, 3x8 is for only one (single or dual)? can you clear this for me?

    clock chip needs a different configuration

    and so in my case (3x8 and due to the my devicetree I posted in previous response) what is this configuration?

    thanks

  • so 2x6, 2x8, 3x6, 3x8 is for only one (single or dual)? can you clear this for me?

    Those are valid values for single and dual link, as long as you don't violate the max channel NCO clock rate of 1540 MHz.

    and so in my case (3x8 and due to the my devicetree I posted in previous response) what is this configuration?

  • so 2x6, 2x8, 3x6, 3x8 is for only one (single or dual)? can you clear this for me?

    Those are valid values for single and dual link, as long as you don't violate the max channel NCO clock rate of 1540 MHz.

    and so in my case (3x8 and due to the my devicetree I posted in previous response) what is this configuration?
